"In this special Halloween video tutorial, we have recreated the idea
behind a musical instrument called the theremin, and built one into a
Halloween costume. This not only gives you the ability to wear a
costume that is loud and very likely obnoxious, but also to have a
costume that is fun for others to interact with. The project uses two
infrared distance sensors, as well as PWM (Pulse Width Modulation) and
a piezoelectric buzzer to create a sound, and brings together quite a
few concepts to make the whole thing work."
